Two identical short bar magnets, each of magnetic moment , are placed perpendicular to each other at a distance apart. The magnetic field at a point midway between them on the line joining their centers is:
\frac{\sqrt{5} \mu_0 M}{2\pi d^3}
\frac{2\sqrt{5} \mu_0 M}{\pi d^3}
\frac{2 \mu_0 M}{\sqrt{5}\pi d^3}
\frac{4\sqrt{5} \mu_0 M}{\pi d^3}
